Step 1: Fake warning message

Ok first we will start with the easy one, the fake warning message.This is how to do it:1.Open note pad2.Type this in@echo offmsg * Warning your computer has detected a virus.msg * To remove the virus click OK or close this boxmsg * Your Hard drives are now being formattedmsg * Please wait ...........msg * APRIL FOOLS

3.Save the file as April-fools.BAT 4.Right click on the file and press hidden 5.Go to folder options and click show hidden files6.Cut the file and place it in the victims Start up folder in the start menu7.Go back to folder options and click do not show hidden files.

Now what each of the lines you typed in done:@echo off << this runs the commands in the background so the victim will not see any codesmsg * <<this commands the computer to show a messagemsg * hahahah <<this is what the message will display

The resultswhen the victim starts up there computer the first message will appear, when they click OK the next one will appear and make the victim think there hard drive is being formatted until they get the last message saying APRIL FOOLS.

Nevermind I looked it up my sister pranked me she added a registry which crashes ur system upon holding ctrl and pressing scroll lock twice. She placed my mouse on the control button and when i wanted to press scroll lock it didnt work so i pressed it again and BAM! BSOD.

Make your batch script start a shutdown and use the task scheduler to have a matching "shutdown -a" (which aborts) so you just freak them out and don't mess with their stuff. This also makes a nice option to have super long shutdown lengths (like your computer will shutdown in one hour! Just so they can massively fail at stopping it lol)
